GAZA CITY (AP) – The Israeli military says its warplanes have struck targets in the Gaza Strip in response to rocket fire toward southern Israel.

The air strikes early Wednesday morning were the first launched by Israel since an informal cease-fire in November ended eight days of cross-border fighting, the bloodiest between Israel and the Hamas-ruled Gaza Strip in four years.

An Israeli military statement said its planes targeted “two extensive terror sites” with “accurate hits.”

Palestinian officials say no one was hurt in the air strikes and no damage was reported in northern Gaza.

The air raids followed the third successful rocket attack on Israel since the November cease-fire.

There was no immediate claim of responsibility for the rocket fire. The Israeli military says it holds Gaza’s Islamic Hamas rulers responsible for any attack against the Jewish state.
